JOSEPH LEE, OF BROOKLYN, NEW YORK.

SCREW INSERTER AND REMOVER.

To all whom it may concern:

Be it known that I, JOSEPH LEE, a subject of the King of England, residing in the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Screw Inserter and Remover, of which the following is a specification.

My invention relates to a tool to be used for holding screws and inserting them in locations where they cannot be started by hand, and also for removing screws from such locations after having been loosened by an ordinary screw-driver.

My object is to produce a tool of this kind which will be simple and cheap in construction and effective in use.

In the accompanying drawing Figure 1 is a view in elevation showing my improved tool. Fig. 2 is a perspective view showing the end of the tool; and Figs. 3 and 4 are plan views showing a screw located in a recess and illustrating the method of applying the tool to the screw slot.

Referring to the drawing, in the particular embodiment of my invention therein shown, my tool consists essentially of a length of metal tubing 5, preferably of soft steel, one end of which is flattened. One edge of this flattened portion is removed by being filed or ground away so as, in effect, to slit one edge of the flattened portion of the tube. The two parts of the flattened end are then spread along the slit edge so as to form leaves 6 and 7 which are joined along the other edge, as clearly shown in the drawing. These leaves 6 and 7 form a laterally folded spring of V transverse cross-section, and may be tempered so that they will always tend to return to the position in which the leaves 6 and 7 are spread, as shown in Fig. 2. The ends of the leaves are squared so as to give a bearing their full width in the slot of a screw. The tubing 5 may be mounted in a suitable handle 8 provided with a finishing ferrule 9. It is, of course, obvious that the tool need not necessarily be made from tubular stock. It might be made from many other kinds, for example, flat stock folded longitudinally.

WVhen it is desired to use the tool for inserting or removlng a screw in a location such as that illustrated in Figs. 3 and 4 in Specification of Letters Patent.

Application filed July 22, 1910.

Serial No. 573,164.

which the screw hole is at the bottom of a cavity 10, the spring leaves 6 and 7 can be readily pressed together by first inserting in the screw slot the corner of the tool at which the leaves 6 and 7 are connected, and then forcing the remaining portion of the tool end into the slot. It is, therefore, never necessary to pinch the spring leaves together by hand, and the tool is, therefore, particularly useful for removing screws which are located in a cavity which is too deep and small to admit the fingers of the workmen. After the end of the tool has been inserted in a screw slot, the expanding pressure of the leaves 6 and 7 on the sides of the slot will hold the screw firmly in line with the tool, thereby permitting the screw to be readily inserted or removed. lVhen the tool is used for inserting a screw, the screw can be turned in its hole until the friction becomes great enough to require the strength of an ordinary screw driver, when the tool should be removed and the screw turned home by an ordinary screw driver, which should also be used initially when a tight screw is to be removed.

WVhat I claim is:

1. A screw inserter and remover having an end provided with spring leaves of V cross-section taken transversely of the axis of the tool.

2. A screw inserter and remover having an end provided with spring leaves joined along one edge longitudinally of the tool and diverging from that edge.

3. A screw inserter and remover, composed of metal tubing, having its end flattened and one edge of said flattened portion slit and spread, substantially as set forth.

4. A screw inserter and remover, composed of metal tubing flattened at one end, the flattened portion being slit along one edge and the two parts thereof spread to form spring leaves connected along the other edge of said flattened portion.

This specification signed and witnessed this 21st day of July, 1910.

JOSEPH LEE.
